Under the optimum conditions, the liner range is 0 to 200 mg/L for BSA and 0 to 125 mg/L for HSA, the molar absorptivity is 1.61×10^5 Lmol^(-1)cm^(-1) for bovine serum albumin and 1.75×10^5 Lmol^(-1)cm^(-1) for human serum albumin. Based on this, a new method is proposed to determine protein. After the method is applied in the determination of the total proteins in real human serum samples, the results are in good agreement with the Kjeldahl method.

Results The latent phase of the primary culture cells was 5-9 days, followed by 11-16 days of logarithmical proliferation; the plateau began at day 18-20. The subcultures showed 12-24 hours of latent phase, followed by 7-10 days of logarithmical proliferation, then entered the plateau (11-13 days). The hMSC expressed positive CD44 unanimously, but don′t expressed CD45. Low concentration of bFGF (10 μg·L-1) could stimulate the proliferation of hMSC significantly (P.05); while 25-100 μg·L-1 of bFGF could inhibit the ALP activity.
